Jewelry professionals use a magnifier, also called a loupe (pronounced loop), to inspect gemstones and other jewelry. These magnifying loupes have special lenses that allow our eyes to focus on an object at a much closer distance than is normally possible, making the object appear to be larger and revealing tiny details we couldn't see with our normal vision

This just means the percentage of a particular metal in the jewelry piece, usually silver or platinum. Marked 900 means there is 90% pure silver or platinum mixed with other alloys, as pure silver is very soft, and cannot be used for making jewelry pieces or anything else, without another metal to give it strength, such as copper.

That means that the silver that it is made of is 92.5% pure; the highest level of purity in jewelry. Silver with higher levels of purity are too soft and are easily scratched and bent to be useful.

Many gems are cut in South Asia, where labour is cheap.

Gems are put upon a piece of wax. This is called a dop. It is stuck onto an arm of a machine which is then lowered onto a turning disc covered with diamond dust or other grit.

Stamped 55 on gold ring

1)You can just buy it and have it sized afterwards

2) Most rings come new at size 6 because about 1/2 of women are that size on at least 1 finger. Thus you can get lucky

3) You can borrow a ring and find out what size it is already. Then get the ring sized to that size

4) Ask a friend or relative of hers

Any gemstone that is set in jewelry that is worn next to the skin usually has a hole in the setting, which allows liquid cleaner or steam to circulate around the stone to clean it.

The gemstone so mounted does not have to be a genuine or precious gemstone, simply one that should be cleaned.

Pure gold is not practical for most jewelry applications because it is too soft so other metals are added to make it harder. Items that are marked "P" for plumb means that it has more gold in it and thus more valuable so 10kp is more valuable than 10kt.

I recommend a strong and durable wood depending on use, if it is a tool box you carry from job to job, or a bench top/roll-a-round. Oak and or Ash is a good choice, keep in mind that its not so much the type of wood, but what kind of joints, I suggest box joints or dovetail. With these type of joints and the glues we have today most any wood will do, you can even make it out of manufactured wood, (MDF, Particle Board, Plywood, etc.)

I have made several out of the latter and they show no signs of wear, (I used butt joints with biscuits and Titebond III glue)

Drywall is commonly calcium sulfate dihydrate, or gypsum. Nowadays there are other types, notably flue gas desulfurization (FGD) drywall and 'Lite' drywall containg ash.

3-M #330 epoxy Glue. it is water clear.

Be sure to use a leather pad between the stone and the finding or bizzel cup.

this well give a shock point for the stone to move and it should n`t break as easy...........

Well it depends on the amount of work and what kinda jeweler you are I know a guy who has a business and is a jeweler just small local one and makes 300,000 dollars my cousin was a jeweler and made 130,000

Real 925 sterling silver jewelry consists of 92.5 percent pure silver with kind of alloy, typically copper.a layer of silver is placed over another metal or alloy, and can be scraped off or tarnished easily.

A human picked up a raw gem-quality diamond and admired it probably 6,000 years ago.

Over time, raw diamonds of gem-stone quality were mounted in metal initially for royalty, because only royalty could afford such adornments. Although there were probably diamond rings crafted before this period, you can view a natural diamond set in Midieval times -- about the 15th century, below.

Emerald is the green variety of beryl. Beryl comes in many colors, like blue, red, yellow.

There are so many different types of jewelry that this question is effectively impossible to answer. Jewelry can be made from almost anything, come in practically any shape or size, and can be handcrafted or mass-produced by machine.

A piece of string with a couple beads on it that you tie around your neck is jewelry. So is a carefully crafted diamond ring. So is a factory-produced plastic bracelet. There are more differences than similarities in the crafting of jewelry, so there is no one way in which jewelry is made.

A jeweler's lens is called a loupe.

No, acetone is not a hardener for resin
